Synchronous replication of virtualized storage processors

摘要

A technique for managing replication of VSPs (Virtualized Storage Processors) proceeds on a per-VSP basis by (i) identifying the data objects associated with a VSP, (ii) establishing a common set of replication settings across all of the data objects associated with the VSP, and (iii) replicating the VSP by replicating each of the identified data objects associated with the VSP in accordance with the common set of replication settings established across all of the data objects associated with the VSP. The technique avoids the need for administrators to separately configure and manage replication on large numbers of individual data objects and thus reduces administrative burdens.

1. A method of managing synchronous replication of VSPs (Virtualized Storage Processors) in a data storage system, comprising:
establishing a first set of synchronous replication settings specific to a first VSP and a second set of synchronous replication settings specific to a second VSP, the first VSP including a first set of multiple data objects and the second VSP including a second set of multiple data objects distinct from the first set of multiple data objects, each data object of the first set of multiple data objects and the second set of multiple data objects being any of a file system, a LUN (logical storage unit), and a vVOL (virtual volume); in response to the data storage system receiving first IO requests specifying data to be written to any of the first set of multiple data objects, synchronously replicating the first IO requests in accordance with the first set of synchronous replication settings specific to the first VSP; and in response to the data storage system receiving second IO requests specifying data to be written to any of the second set of multiple data objects, synchronously replicating the second IO requests in accordance with the second set of synchronous replication settings specific to the second VSP.
